Burning Artifacts
This is verified by posts on the Bay12 forums. Is there a process to go through when removing "verify" tags? The section could also mention that water can put out burning artifacts and that they even burn when part of machinery and similar. – unsigned comment by Vattic
- You can go ahead and remove verify tags if the information is accurate (we don't have strict policies about verification like Wikipedia). —Lethosor (talk) 18:43, 21 January 2014 (UTC)
 Dwarf incineration
I've done some tests regarding how much time a dwarf takes to burn to a crisp, and the results are awkward.
Although it's hard to artificially induce a fire (in Fortress Mode, AFAIK) and to have a dwarf stand idly there being burned, I've somehow used the immolate command and an obsidian wall around a dwarf. After 3 in-game days, there was nothing that remained of said dwarf, except for it's equipment. Dipping them in lava has the same effect, if not quicker.
There also seems to exist a situation where dwarves can exist in a fire-zombified state (e.g. they are in fire, but they don't show signs of it), as stated in Everburning Dwarf Science? and Dwarf is on fire.... Maybe?
I performed some !!SCIENCE!! (literally) with a pet dragon. Dragonfire has a range of 20+ tiles, with a spread of roughly 10 tiles. Dragonfire doesn't appear to expand vertically (though I haven't tried placing the bait on a different z-level yet). Most organic and stone items I blasted with dragonfire either burnt or melted quite quickly. Even nether-cap caught fire (logs, and an unbuilt floodgate). Metal objects, however, seemed to be able to withstand dragonfire. Even non-fire-safe metals, like tin and lead, survived many rounds of dragonfire. A gabbro stone and a chalk door (unbuilt) melted in three breaths, and boiled in three more, yet a tin crown and lead goblet on the exact same tile show absolutely no damage. Since the boiling point of gabbro is significantly higher than the melting point of all metals except adamantine, I'd say there's a bug.--Loci (talk) 20:11, 26 February 2014 (UTC)
- Dragons will target creatures on different z-levels, but their dragonfire cannot actually reach them. This provides a good way to motivate your dragon to breathe fire without requiring periodic replacement of the bait. (The same applies to web-spewing beasts, which should make silk farming slightly more efficient.) Dragonfire does not appear to change the temperature of tiles or items--it appears there may be a special interaction that causes organic items to catch fire and stone items to melt and boil. Metal and water are not affected by dragonfire at all.--Loci (talk) 20:23, 1 April 2014 (UTC)
